ACCORDION REED-BOX.

To all whom it'may concern:

Be it known that I, ZENO BURCH, a citizen of Switzerland, residing at El Centro, in the county of Imperial and State of California, have invented certain new and useful Improvements in Accordion Reed-Boxes, of which the following is a specification.

The present invention relates to improvements in reed boxes for accordions and the primary object of my invention is to provide a new andimproved type of reed box for use in connection with accordions whereby to make more durable the structure of the reed box, to render the same more easily applicable to an operative position and to provide for the utilization of a plurality of reeds and thus amplify the tone of an accordion.

Another object of my invention is to provide a reed box having a novel construction, preferably of metal, and adapted for application to the accordions as now designed without materially altering the structure of the accordion itself.

Other objects and advantages to be derived from the use of my improved reed box for accordions will appear from the following detailed description and the claims, taken with an inspection of the accompanying drawing, in which:

Figure 1 is a fragmental sectional view of an accordion showing a plurality of reed boxes applied thereto;

Fig. 2 is an enlarged perspective view of a reed box embodying the improvements of my invention; and

Fig. 3 is a similar view of one section of the reed box of my invention.

Referring more particularly to the drawing, wherein similar characters of reference designate like and corresponding parts throughout the various views, 10 designates the head of an accordion and 11 the soundplate. Side walls 12 are connected with the head 10 and serve to form a chamber 13 communicating with the bellows 14. A plurality of valve rods 15 of any standard construction are shown.

A plurality of reed boxes embodying the improvements of my invention are shown mounted on the plate 11, said boxes being designated B in their entireties.

Referring to the detail structure of the reed boxes, which latter is best shown in Figs. 2 and 3, I provide a reed box including two detachable sections, S and S. The

Specification 01' Letters Patent.

Application filed November 20, 1916. Serial No. 132,430.

sections S and S are preferably V-shaped so that when said sections are joined a substantially rectangular box is provided. Res ferring to the section S, the same is formed with side walls 16 arranged at right-angles to each other and provided with openings 17 in which the reeds 35 are arranged, as shown on the uppermost reed box in Fig. 1. The walls 16 are providedwith base flanges 18 to afford securement of the section S to a plate, said walls also being provided with a plurality of perforations 19 adjacent the free margins thereof to facilitate'connection of the sections S and S.

The section S is provided with a half-top portion 20 formed with an upstanding flange 21 provided with perforations 22. The section S is provided with side walls 24 arranged preferably at right-angles similar to the walls 16 of the section S, said walls 24 being provided with base flanges 25, said base flanges having perforations 26 therein to facilitate securement of the sections to the sound-board 11. The walls 24 are provided with a plurality of elongated openings 27 to receive reels. The free margins of the walls 24 are provided with anges 28, said flanges being provided with perforations complemental to the perforations 19 in the walls 16, in order that rivets 29 or the like may be inserted therethrough to connect the sections together.

The section S is provided with a half top portion 30 formed with an upstanding flange 31 said flange being perforated complementally to the flange 21 to connect the top portions 12 of the sections S and S.

In use the reed boxes are applied as shown in Fig. 1 and, as in the usual construction of accordion, when the valves are open air is permitted to pass through thereed boxes, vibrating the reeds and producing the music. It will be readily apparent that the construction of my improved reed box facilitates repair of the accordion. The sections from which the reed boxes are formed may be cheaply constructed and owing to the similarity in shape of all the sections the same may be arranged in nested relation and thus readily packed for shipment.

- From the above description taken in connection with the accompanying drawing, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of my invention may be had, and while I have shown and described the device as embodying a specific structure, I desire that it be understood that q such changes may be made in said structure as do not depart from the spirit andscopeof the invention as claimed.

Having thus ,ruu described my inve ntion, what'Iclaini as new and desire to serectangular body, saidsections" having a,
